Process data utilisation for biogas optimisation
Transcript of Process data utilisation for biogas optimisation
Evaluation of process data from operation of real scale biogas plants
Lessons learnt and approaches for practical plant optimisation based on continuous process monitoring ?
Frank Scholwin, Johan Grope
Biomethane - Technology and use
Today: Data accumulate every second
- a monthly evaluation takes place
Average data without quality considerations are used for evaluation - an improved feeling results
Daily data visualize typical fluctuations but also clear effects - surprises in average values get clear
Unlimited Data are online available - substrate feed, gas storage tank, gas production, electricity production, pumps, mixers...
Long Term Efficiency evaluation
Evaluation of process additive (YARA BPO)
Analysis of annual and daily course of heat consumption / flexible operation enables income optimisation
CHP efficiency evaluation
Readout Frequency converter
no failure signal
Overheating Mixer 2
Available data allow weak point analysis
automatisation typically simple after initial detailed analysis
Efficiency control, benchmarking etc. possible
device accuracy, drift and calibration challenging, but internal benchmarking only requires driftless measurements
Basis for plant internal process modelling and prognosis based on historic data is given
Shared Knowledge = increased knowledge!
